Analyse website design

Hello all! Hope you are doing well. I have an existing e-commerce website. Let me tell you a bit more about my website. We are selling custom fit car floor mats for all kind of vehicles. Our company is based in the united states. The website is 80% over , I feel that the website is lacking of some visual professionalism. It looks a bit home made to me. I am not looking at all to redesign it completely, I just think it needs some minor changes to become wonderful and professional, but I don't have that eye to be able to tell. I am looking for someone who can propose me all the changes that can be done to get this website good and rolling!
